CUSHION.

To all whom it may concern Be it known that L MAX Fr'sonrraxn, of

the city of Toronto, in the ccunty'of York,

use with. automobiles, ambulances and the like, having for its object toprovide means whereby the abnormal shockdue to'sudden compression of thecushion will be absorbed, thereby preventing the total collapse of thecushion and the consequent shockto a person who may be seated'the'reon.

Further o j'ects are'to provide for'ftheelimination f noise or contactof the said springs one-with another and {to efiect,' if

desired, the-partial .compressionjof certain 'of said springs inordertoincrease their efiicient operation. f

The invention consists essentially of the novel construction andarrangement. of the parts whereby the primary springs.-f0rining thefoundation of the cushion are reinforced; either directly or indirectly,by further resilient members which may be off strength thanthe'prirnary' springs. Pockets are preferably provided for theaccommodation of the said springs and their reinforcing means, the.springs if desirable being in a state of partial compression Within thesaid pockets and a suitable fibrous material ex tending around the saidpockets both between the same and betweenthe outer covering of thecushion all ofwhich is more particularly described in the followingspecification and with reference to the accompanying drawing in which,-

Figure 1 1s a sectional perspective view of part of a cushion madeaccording to this invention, certain parts being broken away to moreclearly illustrate the structure. Fig,

. is a sectional detail view illustrating the primary spring within oneof the pocketsand a secondary spring concentrically dis posedwithin-said primary spring and also provided with a pocket. Fig. 3 is atransverse section of Fig. 2. Fig. 4 illustrates a method in which theprimary spring may be reinforced and the separate secondaryspring.

dispensed Fig.- 5 illustratesas an ex- .ample anoth-er arrangement ofthe springs,

and' Fig. 6 is a plan of the same;- Similar characters of referenceindicate the several figures .ofthe drawing. 3 6.0 1, 1, are the mainor-primary springs forming the foundation ofjthe cushion and arrangedperpendicularly therein, the. said springs being attached d rectly tothe frame. of the cushion, where such a frame is em- 66 ployed, but itis preferred to dispense with such frame and arrange the springs inv fabric pockets 2, the said fabric pockets being surrounded by feltoiothersuitable fibrous material 3 in such a manner that the internal"I0 construction of the cushion will: be in the .form of a series ofspring containing' rolls A.-A. extending from side to side, th e said"series of rolls preferably beingiui'therr eoveredwith a layer offibrous material f1: be-

-tween the same and the outer coveringbr envelop 5'.

'Where cushions are'so provided with. main Where in connection withautomobiles, it isjlO found that they w ork' very satisfactorily underordinary conditions,- but upon the re hicle passing overa very unevensurface the violent shock will elfect'th'e total collapse of thecushion, beneath the weight of the person seated thereon, the shock"therefore being directly transniitted to the person with consequentdiscomfort.

- In the present case the total collapse of the cushion under suchcircumstances is pre vented by the resilient reinforce-ment'of the saidsprings 1 for a gm of their length. in such manner that after the.primary springsl have been compressed to a certain extent thereinforcementwi ll come into -0 eration, thereby increasing the*"ro or Pv P P tion of forcenecessary for" the further compression of thecushion! The most con venient "form of such resilient reiniorce- 10shorter than the primary springs, although for example, pads of porousrubber or the like may be used for a similar'purpose if desired. Thesesprin sji may be concen trieallyarraingedv witnin the springs 2, or 10-may be integral therewith as indicated in Fig. 4 whereby the primarysprings 2 are.

Theproportionate number of primary and secondary springs may be varieda'ecordmg, to requlrel'nents as Inlay-also the respective positions ofthe said primaryand seeondary sprin g s Fig. of the drawing indicating,

as an example,'an alternative arrangement.

'ith ae'ushlnn of tlus description the required resiliency may heobtained for comfort under ordinary'*eireunwtanees, while- .providingfor increased l'eisista'uee, In the and not in a limiting sensc, exceptas necessitated by the prior art.

What I claim as my invention is:

1. In combination with a eusliion,-lla\'ing primary springs forming thefoundation of said cushion, and secondary springs, substantially shorterthan said primary springs, and upon eommonaxes with said primarysprings, individual pockets also substantially shorter than said primarysprings adapted to retain said secondary springs (10- axially withinsaid primary springs.

In combination with a cushion having primary springs forming thefoundation of said cushion, and secondary springs; substantially shorterthan said primary springs, pockets in which said secondarysprings'areinelosed and n'iaintained in a state of partial .t'ompression.
